Family support groups may be the best messengers to convey the urgent need for brain tissue in autism research, say scientists struggling with inadequate resources.
At 12 months of age, infant siblings of children with autism have a brain response to unfamiliar faces that is characteristic of typical children at a younger age, according to a study published 26 March in Brain Topography. This developmental delay could be used as an early biomarker for autism.
A delayed response to unexpected changes in sound frequency is a marker for language impairment and autism, according to a study published in March in Biological Psychiatry.
There does not appear to be a single genetic or environmental cause of autism, and given the heterogeneity of symptoms, coming up with a clear yes or no test for autism is challenging. Timothy Roberts argues that imaging and electrophysiology are key in the search for autism biomarkers.
Individuals with autism use more brainpower in regions linked to visual perception, and less in those related to planning thoughts and actions, compared with healthy controls, according to a multi-study analysis published today in Human Brain Mapping.
